7 Claims.

rI his invention relates to the formation in concrete masonry, tile, wood and other structures, of

recesses or fitting emplacements in relation to elements to be held in the concrete or other floors, Walls, and other structures. In the present instance the invention is adapted to embody means for facilitating the installation of water closets or other equipment in bathrooms, public toilets and other places. It is particularly designed to enable the ready setting up of closet jobs Where concrete, wood, or tile floors: are cast or built around the roughed-in plumbing job.

In such situations it has heretofore been a source of considerable expense to eiect the proper placement of the floor flange' and closet, where the closet bend is in place and the concrete has been cast, or other structure built closely therearound. A temporary stopper has heretofore been employed to close the end of the job, but it has usually been necessary to cut out some of the concrete or other floor around the pipe or bend. It has not been possible to 'set the floor flange in place on the pipe so` 30 of the floor, the fiange would become disturbed and knocked askew, and then, being held in they floor it is a most difficult job to get it removed, the concrete, tile, or wood cut away, and the sleeve readjusted as required. Also, cement mor- 35. tar would become engaged in the joint, it having been found impracticable to caulk the joint in advance of finishing the floor when the flange is placed, and cleaning of this material to permit proper caulking would be another expensive and 40 time-consuming job, It is not possible to secure the flange to lthe pipe and still permit adjustment of the iiange to the finally established floor level. With my invention I am enabled to cause the formation of a suitable clearance within the 45` concrete around the waste pipe end, preserve the end of the pipe perfectly clean, and enable easy adjustment and caulking of the floor ange sleeve on the pipe in proper position for reception of the closet thereon in the ideal operative relation 50. desired, without expenditure of Work in cutting or cleaning concrete, tile, wood or other material from around or upon any parts of the job, which is an important object of the invention.

Another object of the invention is to enable lithe protection of the waste pipe opening, and

bend or other pipe terminal in the roughed-in the formation of the necessary clearance around the pipe terminal with great certainty and in a manner which will enable its accomplishment by unskilled workmen, and at a small cost for materials, time and labor,Y effecting a consider- 5 able saving in the costs of such installations,

' which is an important attainment, in view of the high cost of plumbing installations now generally involved.

It is a further purpose to provide a novel de- 10 vice for application to the end of a pipe end to attain the ends stated, and others, including the positive support of the device in proper relation to the pipe end so that it will cause a channel to` be formed around the pipe end of ample l5 size to accommodate the necessary plumbing connection elements.

Another aim is to present such device which will enable the positive closure of the pipe end in a manner which will not permit of its being opened accidentally and which will not have objectionable projections to interfere with workmen on various jobs in building construction intervening between the roughing in of the plumbing and the nal emplacement of the closet fixtures or other fixtures.

It is an important object to enable the ready opening of the applied device involved in my invention with the simplest tools, which will always be available conveniently to the job, for plumbers and others requiring to open the device.

Additional objects, advantages and features of invention reside in the construction, arrangement and combination of parts and the manner of use, as will be understood from the following description and accompanying drawing, wherein Figure l is a longitudinal sectional View of the device.

Figure 2 is a botto-m view thereof.

Figure 3 is a sectional view of a typical closet ,1 0 installation incident to new work, at completion of the concrete floor.

Figure 4 is a detail vertical section of the Work last shown at installation of the closet.

Figure 5 is a top view of the device in place in 45` the floor, open for installation of the closet.

Figure 6 is a view similar to Fig. 1, showing a modification. i

There is illustrated a portion of a building structure lil of conventional type, typical of a pri- ,I

vate dwelling bath room closet installation, including joists Il, false floor l2, a waste stack i3 in which a Y, M is included to which leads the outlet from a cast bend I5, the inlet to which comprises a terminal plain cast iron pipe section .15s-i1 I6 which is extended up through the false floor a suitable distance. A concrete floor of usual aggregates and ordinarily formed with Portland cement is cast over the false floor and upper joist portions of the joists and snugly around the pipe It, to a distance above the pipe. Set in the concrete and on the pipe, there is a pipe closer and recess form device I8, shown in greater detail in Figures l and 4.

This closer and form consists of a cylindrical receptacle-like body 20, including the circum Scribing wall 2|, having a concentrically apertured planiform bottom 22 adapted to receive the pipe I therethrough, the bottom adjacent the opening 23 therein constituting a circumscribing continuous horizontal flange. The bottom ange may be formed either integrally with or attached to the wall 2| in a conventional manner according with conventional can manufacturing practice. Fitted on this wall 2| there is a cover 2li consisting of a flat, circular cap plate 25 and a depending circumscribing annular ilange 25, fitting frictionally on the wall 2|, so that the receptacle and cover are held together securely but manually detachable. The cover with its ange may be formed integrally in one piece from sheet metal, as in can or metal box covers.

On the inner side of the top plate 25 there is a depending vertical concentric annular wall 2i, attached by solder or otherwise, firmly to the top plate 25, although it is not necessary that this joint be water-tight or air-tight. The wall 2l may be tap-ered so as to iit freely within the pipe l5 as far as necessary to center the wall 2l in the end of the pipe i6, and to extend within the latter a short distance. The height of the wall 2| issomewhat greater than that of the height of the fitting to be accommodated in the floor, such as the sleeve of the licor flange or collar 28 shown in Figure 4, which includes a top horizontal flange 25 slotted at opposite sides to receive closet fastening screws therein when the closet is secured in place, and a depending sleeve portion 3B, the interior diameter of which is Suniciently greater than the external diameter of the pipe l@ to aord a space for oakum and lead caulking its lower end being slightly restricted to afford a support for the caulking.

The body 2i? and cover parts may be made of comparatively thin sheet iron, and may be tinned to limit corrosion. The top plate 25, particularly, should be of quite thin material, not thicker than roofing tin, although it may be much thinner, and may be of a thickness and material corresponding to that in the tops of cans for canning vegetables, preferably soft iron or other metal that may be readily cut as hereinafter described.

In the use of my invention, the plumbing having been roughed in, including the pipe I6 `permanently in place, and the finished surface level of the completed floor having been ascertained, the closer and form device are put in place by adjusting the opening 23 around the pipe and pressing the device downward with the tapered wall 21 entering the pipe i6 until the plate 25 rests on the pipe, the end of which is adjusted at the iinished floor level. Ii necessary the cover 24 may be separated from the body 2l while the parts are put in place and the cover then adjusted snugly on the wall 2 as in Figures i and 3. If necessary the plate 25 may be adjusted above the end of the pipe |6 and secured or propped at the proper level. If desired one or more small tongues 32 may be formed integrally on the lower inner edge of the flange 22,

turned down and soldered permanently to the pipe I5, or without such tongues the iiange secured by a tack of solder to the pipe I6, or other expedient used.

After emplacement of the device as described, the floor may be cast in place around the pipe IS and the device I8, and tiled flush with the top plate 25, and allowed to become hard set. Other kinds of floors are likewise built snugly around the device abutting closely against the wall 2| or cover. When the closet or other xture is to be put in place, the plate 25 is cut out with a can opener, or a chisel and hammer, or with a hatchet, or a pocket knife, close to the wall 2|, although a portion 33 may be left projecting inward, attached to the flange 25, which is embedded in the concrete and held rmly thereby (see Fig. 4), or as hereinafter indicated, the portion 33 may be connected directly to the wall 2| which corresponds to the wall 2| rst described. If desired, the flange 26 may be crimped at its edges to cause it to become locked in the concrete.

If parts 33 are left they may be irregularly shaped, or serrated, notched, or slitted so that the sleeve 313 of the floor ange may be readily pushed downwardly therethrough, and around the pipe I6 a distance. The caulking is then introduced in the familiar way, either by first packing with oakum and then pouring in molten lead, or by caulking lead wool therein in the familiar way, the iitting being unobstructed so that the caulking chisel may be freely applied. The closet 35 may then be set in place and secured to the ange 29 by the usual bolts and nuts. Usually the iinished concrete floor includes a tiled surface portion 36 applied over the cast concrete Il, and this tiling may also abut the wall 2| and plate 25, so as to underlie the flange 29. Linoleum or rubber sheet flooring also is tted closely around the wall 2| of the device when such flooring is installed.

The top plate 25 may be joined permanently and directly to thewall 2|, as at 25 andI 2| in Fig. 6, so that the whole device is an integral unit except as found necessary to join the parts by seams or other permanent connections. The last mentioned form of the device may be put in place in the saine manner as already described, in one operation, the reduced end of the wall 21' readily entering the pipe I6 after the latter has been projected through the opening 23' in the bottom flange 22'. The top wall 25 and bottom ange 22 may be attached to the wall 2|' by any conventional seam, as at 31|, if desired. The parts in Figure 6 corresponding to those first described have the same reference characters with the addition of a prime mark.

It will be understood that the embodiment presented is purely exemplary, although. it is the best form in which the invention has thus far been embodied, but it may be modified in various ways without departing from the spirit of the invention as set forth in the appended claims.

Thus, to make more secure the hold of the cover 25 on the body 22, any special joints or connections other than the simple friction sleeve iiange 25 may be employed; and the proportions of the device varied to adapt it to use on larger or smaller jointings or mountings of articles in concrete and other structures in such situations asillustrated and various others, the invention not being limited to water connections or joints specically.
